LABELING-MACHINE.

Specification of Letters Patent. Patented Apr. 27, 1920 Application filed January 15, 1916, Serial No. 72,247. V Renewed March 1 1, 1920. Serial No. 365,095.

Fig. 3 is an enlarged top view of the' devices whereby hot cement is applied to cans, or other bodies to be labeled as they enter the machine; and Fig.4 a section of Fig. 3, taken on the broken line w-a: in that figure.

Fig. 5is a view of certain parts'shown in Fig. 1, looking in the direction indicated by the arrow in that figure.

Figs.'6 and 7 are enlarged views of certain details of the machine. 7

Referring now to the-drawings, 1, 1 are bars which are coupled by means of the cross-pieces a and the bolts a to form the frame of the machine; and2 is the wheeled stand which supports the frame.

3, 3 are brackets secured to the bars 1 at the entrance end of the machine, between which is pivoted the base/1 of the chute 5 upon which the cans, bottles or other similar articles to be labeled are placed.

When the machine is not in use the base 4 together with its chute 5 to which it is secured, is allowed to fall into the position shown in Fig. 1; and to adapt the machine for use the chute is elevated so as to make the hole 7) in the base register with the holes 0 in the'brackets 3'; and a rod 7, shown only in Fig. 2, is inserted through the holes to firmly hold the chute in an inclined position.

A similar base 10 with its chute 12 is applied to the delivery end of the machine, and the brackets which. support them are denoted by 1?. r i 7 14, lt are standards shown in section, bolted to the bars 1 of the frame of the machine and which among other uses, not herein enumerated, serve to support the guide rails 15 and 16. The guide rail 15 is in one continuous piece, and furnished with threaded bolts cl which extend loosely and uniformity of adjustment of the said rail, throughout its length, the nuts 6 are provided with a triangular tooth 9 adapted to fit a similarly shapednotch in apro- 'jection forming apart of the standard 14,

as shown in Figs. 2 and 6, and in consequence in turning the nuts, a uniformity of their rotation in adjusting the rail is easily accomplished.

For the purpose of giving the guide rail 16' generally known as the laterally yielding one, a greater flexibility than heretofore found in such devices, I construct the same in detached sections and make each section 16 independently yielding.

To thisend, each section is provided with laterally projecting threaded stems 19 which pass loosely through a bar 20, and loose sleeve 23, and have pins 2' near their ends;v

, encesjn the length of the cans, or any peculiarity in the head joints which practically vaffect their length; V The pot for holding a cement liquefied by heat, is designated by 25, and 1t, to-

gether with the disks which apply the cement to the bodies to be labeled, are now commonly used in labeling machines.

In order'that a predetermined and uniform quantity or thickness of cement will at all times be applied to the disks 26 which are rotated in the pot 25, andtransfer cement to the cans'or other bodies as they are rolled. over the disks, a scraper 28 is hung loosely on the shaft to which the disks 26 are secured; and the distance between the lateral portion 28 of the scraper and the periphery of'the disks will therefore govern the thickness of the dabs of cement applied'to the cans; and in order to prevent the scraper from rotatin with the. disks, i135 is. provided l with: a tai 1 piece:

29 which rests." on thevbottomoi tho pot;

It has been found in transferring labeling machines when the cement in the potis'ina' liquefied condition, from one position to another, that the cement ,isvfrequently splashed from the pot, and .to remedy this, I provide the pot with a plate ofany description having downwardly inclined flanges. h; and as. the liquid cement. is. dashed against. the underside. of these flanges,- it .is turnedflbackr to the .pan without passing .outwardlover the edge.-

271s a-label table offany. ordinary def scriptioma top vie'wof which lS'.Sl10WI1 in Fig. 2, and is mountedlon therupper end of a bar 30 "and guided a. tubularhanger 32 through. which; it passes, and formed ::as

partof the fixed plate .33;

At the loweivendl'oif Ithebar 30 is atread-le.

35, wherebythe table 27 can. be forced down by the foot, to. receivea stack of labels.

The upward .or feeding movement of the label table; is causedlbiy: a. StI'flYpfVV-hiChd S' wound about a spring held sheave 37 as is common an. labehng,mach1nes.

As itzisnecessary in seating; a stackot labels on..the table 27k'that the lattershouldbe temporarilyhelddown, I pivot to-the tubularhanger32. a trigger40 the. vpointof which is adaptedawhentl1e.-table-..is in itslowest position, to automatically enter: a notchuj inathe. bar-.30 and so prevent the rise ofi'th'e table for the .timerbeing;

The. disengagement ofthe trigger from:

the. bar is. easily. effectedby hand, whereupon'thetable. with its stack of'labelswilI rise and the uppermost label be forced-intoalinement with the surface. of the' bed of the machine asis'. commonly done in machines of this class.-

41 .is. the pot .from .which. paste is applied to the labels after they have. been attached by liquefied: cement, to the bodies tobe labeled, and its generalconstruction is old in the. art.

Its novelty consists. in suspending-it by;

means. of i a :rodfrom abracket .43 which is slid on ;a lfiXQCl :stud :44 projecting from-the flange of the machine 45,45 arethe adjustable guides .for the. stack oflabels, and as their function iiswellv known, they, require no descriptionherein.

I' claim as my IIIVGIItIOIl 1. In alabelingmachine, a'frameto and;

fromtwhichxthe can or. body to be 'labeledmay be received and discharged, label distributing and pasting means, and a laterally yielding composite guid rail forthe'rol'li ng cans formed of independently movable sections combined with an opposite springb'acked continuous guide rail, and means to laterally adjust said continuous rail with respect-to said composite rail.
